PAWEL NOBIS, OF BROOKLYN, NEW YORK.

SHIP-PROTECTOR PLATE.

Application filed October 26, 1917.

To all whom it may concern:

Be it known that I, PAWEL blows, a citizen of Russia, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Ship-Protector Plates, of which the following is a specification.

This invention relates to certain new and useful improvements in ship protector plates. 7

The primary object of the invention is the rovision of a ship protector plate made of cheap material most of which is usually considered valueless waste, the completed plate possessing considerable elasticity.

A further object of the invention is the provision of an article of manufacture mainly formed of waste material, the fin ishcd articl possessing elastic qualities and the complete mode of manufacture being easily and inexpensively performed.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a view partly in transverse section and partly in front elevation of a ship provided with my device.

Fig. 2 is a sid elevation thereof.

Fig. 3 is an enlarged vertical transverse sectional view through a portion of the hull and the protector carried thereby.

Fig. 4 is a top plan view of a mold for forming the protecting plates.

Fig. 5 is a vertical sect'onal view taken through the mold when in use and Fig. 6 is a perspective view of a portion of one of the protector plates.

Referring more in detail to the drawing, a ship 10 is illustrated having a hull 11, cabin 12, and funnels 13 while a plurality of plates 14 formed in the manner hereinafter described are preferably resiliently mounted upon the hull 11 by means of outwardlv projecting rods 15 secured to the hull and projecting through the plates14.

Lock nuts 16 are arranged upon the free ends of the rods 15 outwardly of the plates 14 for retaining the plates upon the rods while helical springs 17 encircle the rods 15 and are positioned between the hull 11 and the plates 14 thereby resiliently mounting the plates upon the hull adjacent the water line thereof.

The main object of my invention being the Copies of Specification of Letters Patent.

formation of the elastic plates 14, a boxshaped mold 18 is provided of any desired dimensions having a plurality of upright rods 19 secured to the bottom 20 thereof for the purpose of forming a plurality of perforations 21 in the plates for accommodatk ing the mounting rods 15 carried by the ship. A weighted top or plunger 22 is provided for fitting within the mold 18 and is arranged with a plurality of openings 23 therethrough for accommodating the rods 19.

An elastic plate 14 is formed by first placing a wire net 24 within the mold 18 upon the bottom 20 thereof and then placing a mixture of pine needles and moss cut into small particles and mixed with pitch and united by a small quantity of suitable adhesive material or cement. moss are mixed with the pitch and cement in a warm state and the mass such as 25 is placed within the mold 18 upon the wire net 24, the required amount being furnished to provide aplate having the desired thickness. Another wire net 26 is placed upon the mass 25 and the plunger or presser 22 is inserted in the mold to subject the mass to great pressure for two or three hours, during which time the mass 25 becomes cooled. The mold 18 may be then taken down in any desired manner upon removing the plunger 22 so that the completed plate 14 may be removed for use, the same having the appearance best shown in Fig. 6 of the drawing. This plate 14 as before noted possesses considerable elasticity a well as hardness and toughness rendering it extremely difficult to puncture with projectiles or torpedoes. My article of manufacture is in the nature of a resilient armor plate, and while one manner of employing the same is herein set forth, it will be understood that the same is capable of various other uses.

hat I claim as new is 1. An article of manufacture comprising spaced wire nets, and a mixture of pine needles, moss, pitch, and cement arranged in a compact mass therebetween.

2. A resilient plate consisting of a substantially rectangular compact mass of pine needles, moss, pitch, and cement, and wire nets embedded therein and exposed at the opposite sides thereof.

In testimony whereof I afiix my signature.
